SPECFICATION forming' part Of Letters Patent NO. 401,329, da'ted April16, 1889. Application filed June 30, 1888. Serial No. 278,616. (Nomodel.)

To aZZ whom `it may conoern:

Be it known that we, FRANK. J. CASE and .Lines F. PREsroN, citizens ofthe United States, residing at Arrington, in the county of Atehison andState of Kansas, have invented new and useful linprovements inCar-Couplings, of which the following is a specificaton.

The invention relates to improvement-s in ear-eouplers; and it consistsin the construction and novel combination of parts hereinafterdesoribed, illustrated in the aooompanying drawings, and pointed out inthe appended olaims.

In the drawing's, Figure 1 is a perspeetive view of the end of a earhaving a ooupler emhodying the invention attaehed. Fig. 2 is a centralvert-ioal longitudinal section of the draw-heads thereof. Fig. 3 is aplan view of one of the said draw-heads. Fig. 4 is a perspeetive view ofthe link-bar diseonneeted from the draw-head.

Referring to the drawings by 1etter,A designates the end of a oai'having the draw-bar a, to which the draw-head B is connected in anysuitable manner. The said draw-head has the edges of its monthconverging inwardly, as shown, and is provided in its roof and floorwith the registering longitudinal slots C O', respeetively.

D is a transverse shaft journaled in one of the draw-heads B, just belowthe roof and at the front end of the upper slot, C, which shaft isprovided with the central lever arm or era-nk, d, within the draw-headand the orankhandles (Z' outside of its bearings. The opposite draw-headhas the bearings for the eorresponding shaft D open at top, so that thesaid shaft ean be lifted out of position, if desirable or necessary.

E is the link or eoupling bar, having the vertieal notehes e at equaldistanees from its ends, which not'ohes have reetangular shoul- (lers e'at their onter sides and rounded Shoulders 82 at their inner sides. Thelower edge of the link-bar outside of the said notehes inelines upwardtherefrom, as shown at 83, Fige. The inolined end 83 of the linkharrides np the inelined floor of the month of the draw-head, and theadjacent not-oh e eatohes over the shoulder F, forlned within said monthwhere the latter merges into the roeess of the draw-head.

G is a transverse reotangular engagingframe seated iu a vertiealtransverse reeess,

g, in the draw-head, descending from the for- Ward end of the slotC infront of the shaft D.

H is a oord or wire having its lower end seoured in the eye 71l on theupper edge of said frame and aseendng thenoe through suitable guidesl tothe top of the oar.

When the end of the link-bar enters the draw-head, it lifts the saidframe, and after the notoh e eatehes over the shoulder F the frame fallsin its seat and its upper transverse bar engages on the top .of thelink-bar and holds the latter down on said shoulder. X'Vhen .thelink-bar has entered the draw-head, the

lever-arm or Crank d lies upon its upper surface, and by means of theerank-handles d' the said arm can he depressed upon the entered end ofthe link-bar, and the opposite free end can be inelined upward to eouplewith a higher draw-head.

If desired, the wire or eord H may have lateral extensions passing overpull eys, so that the frame G may thereby loe lifted from the side ofthe ear and the link-bar released therefroin, as well as by drandng saidwire npward from the top of the car.

lelaving described ourinvention, we elaim-- 1. The combination of thedraw-head having the shoulder F and the reeess g, the link engaging theshoulder F, and the frame G, seated in the reeess g and having its uppercross-bar hearing on the-upper edge of the link, the said frame G beingarranged entirely within the draw-head, as set forth.

2. The combination of the draw-headhaving a shoulder, F, the linkengaging said shoulder, the frame G, arranged within the draw-head andengaging the link, and the shaft D, mounted in the draw-head in rear ofsaid frame G and having its crank-arm d resting on the upper edge of thelink, as specified.

3. In a ear-coupler, the combination of the reeessed draw-head providedwith the slots C C', the link-bar E, and the transverse shaft D7provided with the central lever-arm, (Z, and erank-handles d' outside ofits bearings.

In testimony that we olaim the foregoing as our own we have heretoaffixed our signatures in presenee of two witnesses.
